OpenStudy (anonymous):

use 2(wh+lw+lh)

OpenStudy (anonymous):

how do I plug that in?

OpenStudy (anonymous):

w=width l=length h=height

OpenStudy (anonymous):

OpenStudy (anonymous):

divided by 2?

OpenStudy (anonymous):

OpenStudy (anonymous):

@Hero @SmoothMath @timo86m ??

OpenStudy (anonymous):

could you hellp?

OpenStudy (anonymous):

@hero

OpenStudy (anonymous):

i'm just wondering if 240 is right

OpenStudy (anonymous):

thanks

hero (hero):

LA = Perimeter of Base x Height

OpenStudy (anonymous):

so then what is it?

hero (hero):

LA = 2(l + w)h

hero (hero):

LA = 2(l + w)h LA = 2(8 + 6)10 LA = 2(14)10 LA = 28∙10 LA = 280

OpenStudy (anonymous):

thank you soso much!
